Yep the IDAS is the right one and the nosepiece on the qhy8 has the i/r filter built in. The nosepiece is like a normal T-thread to 2" nose but there is a chamber arrangment built into it which has the i/r filter, glued in I guess. They then screw a 48->42 adapter ring onto the end of the nosepiece so it presents a T-thread. That 48->42 ring was constantly coming away from the camera here as I unscrewed various adapters. I'm on the virge of running some silicon around it's thread to keep it in.
